Josh arrived on time to replace a hot water system with a friendly and positive attitude. Josh explained the maintenance process and cleaned up after himself. Job was completed within a very short turn around time from engaging in their services. Professional, competitive company with excellent communication. A credit to Jarred's organisation from his website, quote and invoicing to his staff member Josh. Highly recommended.

Do you want to know more about the Rinnai B26? This review will cut through all the noise to provide you with a clear analysis of energy efficiency, performance, and design. Find out what makes the B26 stand apart from other natural gas water heaters.

The Key Take-Aways

  • The Rinnai B26 is a compact unit that delivers a powerful performance. It can produce 26L/min and has temperature controls for accurate temperature control.

  • It is compatible with solar energy systems, which is more environmentally friendly. The unit requires regular maintenance and professional installation.

Rinnai: The B26 advantage in Japanese design and manufacturing

Rinnai B26, a quality, reliable unit that demonstrates the best in Japanese design and manufacture, is built to last. This unit is not only durable and attractive, but it also helps to maintain the environment. Rinnai B26 reduces greenhouse gasses, creating a more environmentally friendly environment.

Rinnai’s B26 Natural Gas model displays their commitment to energy-efficiency, providing hotwater on demand and keeping operating costs down. The continuous-flow hot water system heats water when it is needed. This reduces energy usage and costs.

Rinnai B26 and Rinnai Infinity 26 are superior to competitors such as Rheem. Japanese manufacturing and design ensure a durable unit, which will deliver endless hot water year after year.

Energy Efficiency: The 6 Star Energy Rating

Rinnai's B26 hot water system combines performance and energy efficiency. It has a 6.1 star energy rating. The rating is determined by factors like the energy supply and type of heating. It is an indication of how well-rounded the system performs in terms energy efficiency.

The high energy rating means that homeowners will save money over the long term and reduce greenhouse gas emissions. This is a win for both your pocketbook and the environment.

The Rinnai B26 gas-fired hot water system is superior to many others, including electric systems. It offers homeowners a cost effective option to reduce their energy costs without compromising performance.

Compact Size, Big Performance

The Rinnai B26 has a powerful performance despite its small size. The Rinnai is a standout in size. Its dimensions are 571mm (including brackets), 35mm wide, and 194mm deep. The compact design makes installation of temperature control cables easier.

Rinnai's B26 is compact and offers a variety of installation possibilities. The Rinnai B26 is ideally suited for homes with limited space. Its efficient design also ensures that it performs well in terms of heating water. Rinnai's B26 is the perfect solution for anyone who lives in a small apartment or wants to save space.

The Rinnai B26 is compact, but it doesn't sacrifice performance. It can produce hot water up to 26L/min and only heats water as needed. You can take a shower at any time without having to worry about not being able to get enough hot water.

Temperature control with optional controllers

Compatible with Rinnai B26 models, optional temperature controllers allow you to set the temperature of the hot water according to your preferences. Add up to four optional temperature controls to the unit to enhance control.

The additional temperature controllers allow users to control the heat precisely. The hot water unit can provide the desired temperature when used correctly. Rinnai B26 is a great choice for a hot bath or shower.

Rinnai B26 provides precise temperature controls and optional controllers can enhance this to provide even greater accuracy. Users have shared their experiences on forums, and it appears that there are no drawbacks to using the optional controllers in conjunction with the energy-efficient Rinnai B26.

Heat exchanger is the core of B26 continuous flow hot water system

Heat exchanger is the heart of Rinnai's B26 system for continuous hot water flow. The heat exchanger facilitates efficient heat transfer between burning gas and water, while making sure they do not mix. This component is essential to the B26’s performance and makes it ideal for home applications.

There is a lot of rust on the Rinnai heat exchanger. It also has a white chalky powder. This might initially raise questions about the condition the heat exchanger. The National Field Support Specialist confirmed, however, that surface rust is normal and will not cause leaks nor affect the heat-exchanger's ability to operate. You can enjoy your Rinnai's B26 hot water with confidence.

Reduce your running costs with natural gas

Natural gas is one of Rinnai B26's most notable features. It allows it to lower operating costs while reducing its environmental impact. The unit can provide hot water continuously with the use of natural gas, which is an efficient fuel.

Rinnai B26 features include:

  • Gas consumption of 199MJ/h - a competitive rate

  • Continuous flow water heaters are a cost-effective alternative.

  • You can enjoy hot water when you want it, without having to worry about expensive energy bills.

Rinnai B26 is the perfect blend of performance and efficiency. This investment will pay for itself over time, with reduced operating costs and minimal impact on the environment.

Installing and Servicing Your Home: Expectations

Installing the Rinnai B26 should be done by a licensed professional, following the guidelines of the manufacturer and the current AS/NZS standard. To ensure optimal performance, it's vital that installation be done safely and correctly.

The Kitchen Water Controller is installed as follows:

  • Temperatures should not be higher than 50degC

  • Follow the manufacturer's instructions for installation and maintenance.

  • If you detect a gas smell, seek professional help.

It is important to hire a professional licensed in gas and water, like JR Gas & Water.

To ensure optimal performance from your Rinnai, we recommend scheduling a service at least every three years. Your unit will continue to operate efficiently and reliably if you perform regular maintenance.

The Future of Hot Water: Solar Compatibility

Rinnai's B26 model is an innovative, forward-thinking product that can be used with solar water heating systems. It acts as a booster gas for Rinnai hot water solar systems. You can integrate the Rinnai B26 with solar systems to ensure your hot water requirements are future proofed.

The Rinnai system B26 can be integrated with solar water heating systems to achieve a variety of benefits, including cost-savings, energy savings and reduced carbon footprint. You can enjoy hot water and contribute positively to the planet.

It is essential that an experienced and qualified professional installs a Rinnai Solar System, preferably a Rinnai Premio or Sunmaster solar water heater. It is important that this system be installed properly to ensure its safety and performance.
